"Organe d'assemblage pour réunir des pièces en bois munies d'une rainure"."Assembly member for joining wooden pieces with a groove".
La présente invention concerne un organe d'assemblage pour réunir des pièces en bois rainurées, organe comprenant - une âme plate munie à l'avant d'une arête de coupe - bordée de deux lames d'assemblage donnant à l'ensem
ble une section en forme de H, ces deux lames
faisant entre elles un angle de pincement négatif
ouvert en direction de l'arête de coupe.The present invention relates to an assembly member for joining grooved wooden parts, member comprising - a flat core provided at the front with a cutting edge - bordered by two assembly blades giving the assembly
ble an H-shaped section, these two blades
making a negative pinch angle between them
open towards the cutting edge.
On connaît déjà de tels organes d'assemblage réalisés en acier. De tels organes s'enfoncent dans la rainure réalisée dans chacune des deux pièces à assembler et le pincement négatif des lames d'assemblage assure le serrage des deux pièces l'une contre l'autre à mesure que l'organe est enfoncé dans son logement, les lames d'assemblage s'accrochant dans les côtés de chaque pièce de bois. Already known such assembly members made of steel. Such members sink into the groove made in each of the two parts to be assembled and the negative pinching of the assembly blades ensures the tightening of the two parts against each other as the member is pressed into its housing. , the assembly blades hanging on the sides of each piece of wood.
Bien que ces organes d'assemblage connus donnent satisfaction, ils présentent un certain nombre d'inconvénients en particulier celui de ne pas être combustibles ou du moins de ne pouvoir être détruits à une température de combustion moins élevée que celle de l'acier. Although these known assembly members are satisfactory, they have a certain number of drawbacks, in particular that of not being combustible or at least of being unable to be destroyed at a combustion temperature lower than that of steel.
La présente invention concerne un organe d'assemblage du type ci-dessus permettant d'assembler efficacement des pièces en bois munies préalablement d'une rainure, soit léger et puisse être détruit à une température de l'ordre de 600 à 800 . The present invention relates to an assembly member of the above type making it possible to efficiently assemble wooden parts provided beforehand with a groove, which is light and can be destroyed at a temperature of the order of 600 to 800.
A cet effet, l'invention concerne un organe d'assemblage--du-type ci-dessus caractérisé en ce que - il est réalisé en une seule pièce en-aluminium pro
filé et usiné - le rapport R = A/B entre l'épaisseur A de l'âme et
l'épaisseur B de chaque lame d'assemblage et compris
entre 0,8 s R < 1,2 - les lames se terminent à l'avant en retrait par rap
port à l'arête de coupe, par une surface arrondie,
tronquée, symétrique.To this end, the invention relates to an assembly member - of the above type characterized in that - it is made in a single piece of pro-aluminum
spun and machined - the ratio R = A / B between the thickness A of the core and
the thickness B of each assembly blade and included
between 0.8 s R <1.2 - the blades terminate at the front, set back by rap
carried at the cutting edge, by a rounded surface,
truncated, symmetrical.
Cet organe d'assemblage en aluminium peut être détruit à une température relativement basse pour ne pas laisser de résidus de combustion autres que les cendres du bois. Cet organe présente une résistance suffisante grâce à sa structure mécanique et au rapport entre son épaisseur et l'épaisseur des lames d'assemblage, structure suffisamment résistante pour assurer l'assemblage et surtout rapprocher les deux pièces à assembler. De plus, un organe d'assemblage présent dans la structure rappelée ci-dessus permet l'assemblage de bois à textures très différentes allant des bois durs aux bois mous. This aluminum assembly member can be destroyed at a relatively low temperature so as not to leave combustion residues other than wood ash. This member has sufficient strength thanks to its mechanical structure and the ratio between its thickness and the thickness of the assembly blades, a structure which is strong enough to ensure assembly and above all to bring the two parts together. In addition, an assembly member present in the structure recalled above allows the assembly of woods with very different textures ranging from hardwoods to softwoods.
Suivant une autre caractéristique de l'invention, le bord longitudinal des lames d'assemblage est plat et les petites faces des lames d'assemblage sont légèrement bombées. According to another characteristic of the invention, the longitudinal edge of the assembly blades is flat and the small faces of the assembly blades are slightly curved.
Suivant une autre caractéristique de l'invention, la section des parties de chaque lame d'assemblage en saillie par rapport à l'âme est en forme de trapèze dont l'hypoténuse est curviligne. According to another characteristic of the invention, the section of the parts of each assembly blade projecting relative to the core is in the form of a trapezium whose hypotenuse is curvilinear.
La présente invention sera décrite ci-après de manière plus détaillée à l'aide des dessins annexés dans lesquels
- la figure 1 est une vue de dessus d'un organe d'assemblage selon l'invention.The present invention will be described below in more detail with the aid of the accompanying drawings in which
- Figure 1 is a top view of an assembly member according to the invention.
-- la figure 2 est une vue de côté de l'organe d'assemblage-de la-figure 1.. - Figure 2 is a side view of the assembly member of Figure 1 ..
- la figure 3 est une vue en coupe très schématique de deux pièces en bois réunies par un organe d'assemblage selon l'invention. - Figure 3 is a very schematic sectional view of two wooden parts joined by an assembly member according to the invention.
- la figure 4 est une vue en coupe de l'extrémité avant de l'organe d'assemblage de l'invention. - Figure 4 is a sectional view of the front end of the assembly member of the invention.
- la figure 5 est une vue en coupe de l'extrémité arrière de l'organe d'assemblage selon l'invention. - Figure 5 is a sectional view of the rear end of the assembly member according to the invention.
- la figure 6 est une vue en coupe transversale partielle de l'organe d'assemblage selon l'invention. - Figure 6 is a partial cross-sectional view of the assembly member according to the invention.
Selon les figures 1 et 2, l'organe d'assemblage selon l'invention se compose d'une âme 1, plate à grandes faces parallèles ; cette âme 1 est bordée de chaque côté par une lame d'assemblage 2, 3 de forme symétrique et qui ne sont pas exactement parallèles mais présentent un léger pincement c'est-à-dire font entre elles un angle s'ouvrant vers l'avant du côté de l'arête de coupe 4. According to Figures 1 and 2, the assembly member according to the invention consists of a core 1, flat with large parallel faces; this core 1 is bordered on each side by an assembly blade 2, 3 of symmetrical shape and which are not exactly parallel but have a slight pinching, that is to say form an angle opening between them. front side of the cutting edge 4.
L'arrière de cet organe d'assemblage 5 est plat et sert à la frappe à l'aide d'un outil tel qu'un marteau ou un outil d'enfoncement par exemple pneumatique. La surface arrière 5 est en saillie par rapport au bord arrière 21, 31 des lames d'assemblage 2, 3 pour qu'à aucun moment l'outil d'enfoncement n'écrase les côtés arrière 21, 31 des lames 2, 3 ce qui risquerait de provoquer la fissuration ou l'éclatement du bois. Il faut en effet que même pendant l'enfoncement, les lames d'assemblage 21, 31 restent rigoureusement planes. The rear of this assembly member 5 is flat and is used for striking using a tool such as a hammer or a driving tool, for example pneumatic. The rear surface 5 projects from the rear edge 21, 31 of the assembly blades 2, 3 so that at no time does the driving tool crush the rear sides 21, 31 of the blades 2, 3 ce which could cause cracking or splitting of the wood. It is indeed necessary that even during the insertion, the assembly blades 21, 31 remain strictly flat.
La figure 3 montre en coupe transversale la mise en place d'un organe d'assemblage dans la double rainure 6 7 réalisée dans deux pièces de bois 8, 9. FIG. 3 shows in cross section the installation of an assembly member in the double groove 6 7 produced in two pieces of wood 8, 9.
Cet organe d'assemblage à section en forme de H, se loge dans la rainure 6, 7 formée par la -réunion des deux pièces en bois 8,--9 et assemble ces deux pièces.This H-shaped section assembly member is housed in the groove 6, 7 formed by the meeting of the two wooden pieces 8, - 9 and assembles these two pieces.
Du fait du pincement négatif des lames d'assemblage 2, 3, les pièces 8, 9 qui sont représentées avec un écartement 10, exagéré (mais -qui sont en réalité plaquées l'une contre l'autre), sont resserrées du fait du pincement de l'organe d'assemblage.Due to the negative pinching of the assembly blades 2, 3, the parts 8, 9 which are shown with an exaggerated spacing 10 (but which are actually pressed against each other), are tightened due to the pinching of the assembly member.
Cet organe d'assemblage est, selon l'invention, en aluminium. This assembly member is, according to the invention, made of aluminum.
Selon l'invention et comme représenté aux figures 4, 5 et 6, l'épaisseur A de l'âme 1 et l'épaisseur B des lames de coupe 2, 3 est un rapport R compris entre 0,8 et 1,2 ; ce rapport est de préférence égal à 1. Comme les petits côtés 11, 12 des lames 2, 3 sont parallèles et que l'âme 1 a des grandes faces 1', 1" également parallèles, ce rapport est respecté sur toute la longueur de l'organe d'assemblage ainsi que dans son épaisseur comme cela est indiqué aux figures 4, 5 et 6. According to the invention and as shown in Figures 4, 5 and 6, the thickness A of the core 1 and the thickness B of the cutting blades 2, 3 is a ratio R of between 0.8 and 1.2; this ratio is preferably equal to 1. As the short sides 11, 12 of the blades 2, 3 are parallel and the core 1 has large faces 1 ′, 1 "also parallel, this ratio is respected over the entire length of the assembly member as well as in its thickness as indicated in FIGS. 4, 5 and 6.
La figure 4 montre également que les lames d'assemblage 2, 3 se terminent à l'avant par une partie arrondie (représentée en pointillés 13, 14) qui a été tronquée 15, 16 pour favoriser l'enfoncement et l'écartement du bois au passage de l'organe d'assemblage. Ces parties tronques 15 et 16 assurent également un meilleur guidage de l'organe d'assemblage au moment de son enfoncement. Figure 4 also shows that the assembly blades 2, 3 end at the front with a rounded part (shown in dotted lines 13, 14) which has been truncated 15, 16 to promote the penetration and spacing of the wood the passage of the assembly member. These truncated parts 15 and 16 also ensure better guidance of the assembly member at the time of its insertion.
Comme le montre en outre la figure 6, la surface des petits côtés 11, 12 des lames d'assemblage 2, 3 est arrondie. Cette figure montre également la forme de trapèze curviligne des parties 17, 18 de forme trapézoïdale des lames d'assemblage dépassant de l'épaisseur de l'âme 1. Ils'agit d'une forme assimilable à un trapèze dont l'hypoténuse 19, 20-est curviligne. As further shown in Figure 6, the surface of the short sides 11, 12 of the assembly blades 2, 3 is rounded. This figure also shows the shape of a curvilinear trapezoid of the parts 17, 18 of trapezoidal shape of the assembly blades protruding from the thickness of the core 1. It is a shape comparable to a trapezium whose hypotenuse 19, 20-is curvilinear.
La présente invention s'applique en particulier à l'assemblage de tout type de pièce en bois, qu'il s'agisse de bois dur ou de bois mou (chêne, sapin) après que lton ait réalisé des rainures à des endroits homologues dans les surfaces en regard des pièces à assembler (figure 3). The present invention applies in particular to the assembly of any type of wooden part, whether it is hard wood or soft wood (oak, fir) after lton has made grooves in homologous places in the facing surfaces of the parts to be assembled (Figure 3).
